[tex]\frac{m}{f}[/tex] = [tex]\frac{m}{f}[/tex]

Compare the ratio with the actual numbers.  Solve for the missing number

[tex]\frac{7}{9}[/tex] = [tex]\frac{m}{54}[/tex]  you need to multiply 9 by 6 to get 54 so multiply 7 x 6 to get 42.

[tex]\frac{7}{9}[/tex] = [tex]\frac{63}{f}[/tex]  Multiply 7 x 9 to get 63,so multiply 9 by 9 to get 81.

[tex]\frac{7}{9}[/tex] = [tex]\frac{m}{117}[/tex]  9 x 13 is 117, so multiply 7 by 13 to get 91.

Answer:

The probability that you draw two balls that are both black is [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

To find probability, take the number of desirable outcomes over the total number of possible outcomes.

In this case, the black balls are desirable. There are four of them.

this means the numerator of the first fraction is 4. The denominator is the total possible outcomes or in this case the total number of black and white balls. This number is 9. The first probability fraction is [tex]\frac{4}{9}[/tex]

Lets say that the first one was black. Now we need to find the probability of drawing another one. Now there are black balls left in the bag. This means that the number of desirable outcomes is 3. There are also 8 balls total. This means the number of total possible outcomes is 8. The second probability is [tex]\frac{3}{8}[/tex]

To get the total probability you multiply both of the individual probabilities together.

[tex]\frac{4}{9} *\frac{3}{8} =\frac{1}{6}[/tex]

When the given numbers are ordered from least to greatest, the result would be 8/25, 1, 5/4, 1.3

To be able to order the numbers, it would be best to convert them to the same form. In order words, all the numbers should either be decimals or fractions.

Decimals are easier to compare so convert them to decimals:

= 8 / 25                                                    = 5 / 4

= 0.32                                                      = 1.25

The numbers are:
1, 0.32, 1.3, 1.25

The order from least to greatest is:

0.32, 1, 1.25, 1.3

The most appropriate choice for tangent to a curve will be given by- 2x + 25y = 10 is the required equation of tangent.

What is tangent to a curve?
In geometry, a tangent line is a straight line that most closely resembles (or "clings to") a curve at a particular point. It could be thought of as the limiting role of straight lines that pass through the specified point and a nearby curve point as the second point gets closer to the first. If two curves share the same tangent at a given point, they are said to be tangent. Similar definitions apply to the tangent plane to an exterior at a point and two surfaces that are tangent at a point.

Equation of  tangent to a curve at a point [tex](x_1, y_1)[/tex]  is given by

[tex]y-y_1 = \frac{dy}{dx}|_{(x_1, y_1)}(x - x_1)[/tex]

Here,
f(x) = [tex]\frac{2}{x}[/tex]
f'(x) = [tex]\frac{d}{dx} (\frac{2}{x})[/tex]

     = [tex]2(-1)x^{-1-1}\\-2x^{-2}[/tex]

[tex]f'(x)|_{(5, 0)} = -\frac{2}{5^2}[/tex]

               [tex]= -\frac{2}{25}[/tex]

Equation of tangent

The domain of the function is 1 ≤ x < 2.

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates).

We have f : [tex]\frac{1}{\sqrt{x-1} } + \frac{1}{\sqrt{2-x} }[/tex]

[tex]\sqrt{x-1}[/tex] ≥ 0

x- 1 ≥ 0

x ≥ 1

Similarly , [tex]\sqrt{2-x}[/tex] > 0

Apply the multiplicative law of distribution.

Rearrange the unknown terms on the left side of the equation.

Combine as terms

Calculate the sum or difference.

Divide both sides of the equation by the coefficient of the variable.

The answer is x = - 9/4. Because if we do the division, the result is not exact; means that the result is decimal.

Answer:

x = -9/4

Answer:  square root of 104

Step-by-step explanation:

The length of the missing side in the right triangle is approximately √104.

Given is a right triangle with one leg labeled 11 and hypotenuse labeled 15.

We need to find length of the missing side.

To determine the length of the missing side in the right triangle, we can use the Pythagorean theorem.

It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Let's denote the missing side as "x".

According to the given information:

One leg (one of the shorter sides) is labeled as 11.

The hypotenuse (the longest side) is labeled as 15.

Using the Pythagorean theorem, we can set up the equation:

11² + x² = 15²

Simplifying this equation:

121 + x² = 225

Subtracting 121 from both sides:

x² = 225 - 121

x² = 104

To find the value of "x," we can take the square root of both sides of the equation:

x = √104

Therefore, the length of the missing side in the right triangle is approximately √104.

Answer:

9 students

Explanation:

Every 8th person that entered the cinema received a free ticket.

The number of students who entered in the first hour = 76.

The first person given a ticket was the 8th person.

To calculate the number of persons who received a free ticket, we can view this problem as an arithmetic sequence in which:

• The first term = 8

• The last term = 76.

• The common difference (every 8th person) = 8.

Using the formula for the last term of an arithmetic sequence, we have:

Our goal is to find n, the number of students.

Since the number of students that entered in the first hour is not more than 76, we have that:

9 students received a free ticket.

The meand and variance are 13.75 cm and 17.52 respectively.

Each possible outcome is equally likely when there is a uniform probability.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean of the uniform distribution is:

M = ( a + b ) / 2

The variance of the uniform distribution is given by:

V = ( b - a )² / 12

Uniform distribution on the interval ( 6.5, 21 )

Therefore, a = 6.5 and b = 21

Hence, the mean will be:

M = ( 6.5 + 21 )/ 2

M = 27.5 / 2

M = 13.75

The mean of depth is 13.75 cm.

The variance will be:

V = ( b - a )² / 12

V = ( 21 - 6.5 )² / 12

V = 210.25 / 12

V = 17.52

The variance of depth is of 17.52 cm².

Answer: The answer is 76

Step-by-step explanation:

Answer: y = 3x +1

Step-by-step explanation:

y =mx +b

m(slope) = 3

b(y-int) = ?

y = 3x+b

substitute in values

4 = 3(1) +b

4 = 3+b

b = 1

y= 3x+1

The slope of the line that passes through the points (10,10) and (5,10) is 0

Slope is simply expressed as change in y over the change in x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1 ( 10,10 )

Point 2 ( 5,10 )

To determine the slope, plug these coordinates into the slope formula and simplify.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 10 - 10 )/( 5 - 10 )

Slope m = ( 0 )/( 5 - 10 )

Slope m = ( 0 )/( -5 )

Slope m = 0

Therefore, the slope of the line is 0.
